I had this on a BMW front light after someone knocked the side of it cracking the seal. I used low modulus glazing sealant from screwfix and it seems to have worked. I think the low modulus means it is less stiff when it sets so less likely to fail.

Yes, I read it as a "flexible" sealant.
Which one did you buy, do you have a link?
I'm looking at outside/inside sealers and my second post, the sealant can withstand high and extremely low temps and is UV resistant.I appreciate your time.

This is the stuff.

My son's Fiat Punto has combined LED and normal rear lamps which got water in them. I just drilled a hole in the bottom of the lamp housing to let any moisture escape. They've been fine for the last 6 years.

Thanks - I've read on the net about others doing that and it worked.  The problem with this car is when I looked at the blown up pictures there are cirut boards near the bottom as it is fully LED.

How big is the hole you drilled? Sill question but the light unit is long and big  - I was thinking 1mm would be too small and 5mm too big and possibly try a 3mm hole?

The Punto light unit is tall and thin, I think the hole is about 3mm. Just make sure the hole drains outside the bodywork. I would have preferred to seal it if possible, the hole was a bit of a last resort, but I'm surprised how long it's lasted.

Cheers. I've looked and looked on the net but nothing re my rear lights ie pull apart etc. Today I will take the leaky one off first and I doubt I will be drilling as the less appears to be right across the bottom and side. I have bought a deep socket to fit over the long thread and yesterday I was able to access all nuts and today I will take them off. I've bought a LMN silicone sealant.

I doubt I will be able to get the water out without drilling but I will try that first.  
I will take the other rear light out as well if I can access it and put sealant on that as a preventative.

I fixed it in early March. Used a clear sealer that have good reviews and this sealer remains slightly flexible.
I did not need to drill and holes. I used a har dryer and then kept the taillight in the sun and all of the water/moisture etc went away.
I needed a deep socket which I did not have. When a looked online a socket, single deep socket for the size I needed cost from 6 to 12 pounds. I bought a 50 piece rachet set for 10 or 11 pounds inc postage and that has been used on other projects since.

How do you know that it hasn’t been in any accidents?

Have you known of the car since it was new?

simple - when i took off the light there were no cracks etc and the bodywork outside the light and inside the light was straight and original - this was supported by the fact there was no overspray etc anywhere on the car/ight etc etc
